The five golden leaves are a set of quest items in the game The Legend of Zelda: Link's Awakening. Link comes to a villa south of the pothole field. Inside is a man named Richard and a multitude of frogs. Richard tells you that he used to live in Kanalet castle, and ask you to retrieve the five golden leaves that he left there. Once Link does so, Richard gives him the Slime Key to access Key Cavern, the next level!!!
